Constructor Detail

IntegerChromosome

protected IntegerChromosome(ISeq<IntegerGene> genes)

Create a new chromosome from the given genes array.

Parameters:

genes - the genes of the new chromosome.

Throws:

IllegalArgumentException - if the gene sequence is empty

NullPointerException - if the genes are null.

IntegerChromosome

public IntegerChromosome(Integer min,
                         Integer max,
                         int length)

Create a new random IntegerChromosome.

Parameters:

min - the min value of the IntegerGenes (inclusively).

max - the max value of the IntegerGenes (inclusively).

length - the length of the chromosome.

Throws:

NullPointerException - if one of the arguments is null.

IllegalArgumentException - if the length is smaller than one.

IntegerChromosome

public IntegerChromosome(Integer min,
                         Integer max)

Create a new random IntegerChromosome of length one.

Parameters:

min - the minimal value of this chromosome (inclusively).

max - the maximal value of this chromosome (inclusively).

Throws:

NullPointerException - if one of the arguments is null.

Method Detail

toArray

public int[] toArray(int[] array)

Returns an int array containing all of the elements in this chromosome in proper sequence. If the chromosome fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the length of this chromosome.

Parameters:

array - the array into which the elements of this chromosomes are to be stored, if it is big enough; otherwise, a new array is allocated for this purpose.

Returns:

an array containing the elements of this chromosome

Throws:

NullPointerException - if the given array is null

Since:

3.0

toArray

public int[] toArray()

Returns an int array containing all of the elements in this chromosome in proper sequence.

Returns:

an array containing the elements of this chromosome

Since:

3.0

of

public static IntegerChromosome of(IntegerGene... genes)

Create a new IntegerChromosome with the given genes.

Parameters:

genes - the genes of the chromosome.

Returns:

a new chromosome with the given genes.

Throws:

IllegalArgumentException - if the length of the genes array is empty.

of

public static IntegerChromosome of(int min,
                                   int max,
                                   int length)

Create a new random IntegerChromosome.

Parameters:

min - the min value of the IntegerGenes (inclusively).

max - the max value of the IntegerGenes (inclusively).

length - the length of the chromosome.

Returns:

a new random IntegerChromosome

Throws:

IllegalArgumentException - if the length is smaller than one

of

public static IntegerChromosome of(IntRange range,
                                   int length)

Create a new random IntegerChromosome.

Parameters:

range - the integer range of the chromosome.

length - the length of the chromosome.

Returns:

a new random IntegerChromosome

Throws:

NullPointerException - if the given range is null

IllegalArgumentException - if the length is smaller than one

Since:

3.2

of

public static IntegerChromosome of(int min,
                                   int max)
